You and ghost were on the battlefield. As you two walked around looking for the enemy ghost spots one of them pointing their gun at you ready to shoot at any given moment.

Ghost grabs your arm and pulls you behind an old wall. As fall against his chest you hear his hear beat for the first time. Something about his heart beat was so comforting...so soothing. Everyone only seen him as a heart less soldier that only cared about himself. Simon just let you listen. It was if he knew you loved it.
